So for planning for a (3-5yr) converged network (data, voice, and video) was is the important elements to consider as far as what type of bandwidth would be needed on the LAN, WAN, and Internet. Currently have 10/100 backbone, 10MB and 43MB WAN links, and 15MB Internet pipeline.
I am thinking 1GB backbone, 10GB core, 100MB WAN, and at least 100MB internet pipeline. Obviously, the more the better, but do not want it to be an overkill.
Any suggestions or input.
